Loved these! I used half red and half white potatoes, and increased the spinach to potato ratio to suit what I had on hand. Do not forget the nutmeg or the chives, they both added to the taste. Instead of sour cream I used a thick Greek low-fat yogurt. I also left the potato skins on and liked the resulting texture. I have a potato ricer but not a masher so I just used the back of a slotted spoon. BF liked this recipe too but was a little bit cooler about it than I was. Besides, he likes his mashed potatoes skinless and smooth and I like them just the opposite:D He's not rating this recipe either;)
